Thermal storage for homes · Aberdeen
Buy your heat at night. Use it all day.
Heatloop is a thermal battery the size of a fridge. It charges from cheap off-peak electricity, holds the energy as heat in a phase-change store, and warms your radiators and hot water whenever you need it.

Three steps, every day, without you thinking about it.
Electricity is cheapest when the country is asleep and the wind is still blowing. Heatloop buys it then, and your home doesn’t notice the difference at teatime.

Step 01 · 00:30–07:30
Charge on the cheap rate
The controller reads your tariff and charges when power is cheapest, usually overnight and sometimes for an hour after lunch.
-
Step 02 · up to 28 kWh
Hold it as heat
Sealed cells of a salt-based material melt at 58°C and soak up energy as they do. Vacuum panels keep it in for the day.
-
Step 03 · whenever you like
Release it to radiators and taps
Water runs through the copper exchanger and comes out at up to 62°C, to the radiators you already have and to your hot taps.
Move most of a cold day’s heat into the cheap hours.
Pick a model and slide to the heat your home uses on a cold winter’s day. A typical three-bedroom semi in Aberdeen uses about 46 kWh.

of a 46 kWh day’s heat could be bought at the cheap rate: 33.5 kWh, with 12.5 kWh at the day rate.
An estimate for a cold day, assuming 12% of the day’s heat is used during the cheap hours anyway. Real results depend on your home, your tariff and the weather.

“The most convincing answer we’ve seen to the question of what replaces a combi boiler in a two-up, two-down.”
“A quiet box that does its shopping at three in the morning. The engineering under the panel is anything but quiet.”
“Aberdeen built a century on oil. Heatloop is one of the companies betting on what comes next.”
